Reversible reaction?

A reversible reaction is a chemical reaction in which the products can react to reform the original reactants. This means that the reaction can proceed in both the forward and reverse directions. The reaction reaches a state of dynamic equilibrium, where the rates of the forward and reverse reactions are equal. Examples of reversible reactions include the formation of water from hydrogen and oxygen gas, and the dissociation of ammonium chloride into ammonia and hydrogen chloride gas.
